The exact causes of chronic kidney failure are unknown, although the debilitating loss of healthy kidney tissue may be a natural endpoint for several readily recognizable conditions, including advanced dental disease and a variety of kidney infections, inflammations and obstructions.
Sodium chloride was needed to ensure the proteins in the cell aren't separated from the rest of the solution with the DNA. Okay, the person above does not understand Chemistry nor the English language. The sodium chloride, NaCl, is a polar molecule, which would help separate an emulsion of two layers in an acid-base extraction. Since NaCl is polar, it would be easily dissolved into the solution and tie up the different layer molecules.
Application. One technique that scientists can use to concentrate DNA or RNA is called ethanol precipitation. In an aqueous (liquid) solution of DNA or RNA, salt and ethanol can be added to the solution and the nucleic acid precipitates out of the solution.The solution is then centrifuged and the nucleic acid forms a pellet separate from the solution.n an aqueous (liquid) solution of DNA or RNA, salt and ethanol can be added to the solution and the nucleic acid precipitates out of the solution.
